A black hairy tongue is caused by too much bacteria or yeast growth in the mouth: the bacteria build up on tiny rounded projections called papillae. These lie along the surface of the tongue. Instead of shedding as they normally do, the papillae start to grow and lengthen, creating hair-like projections.
It may happen slowly, but you canât help but notice a black, âhairyâ patch forming on your tongue. In fact, itâs so alarming that youâll have to ask yourself: What causes black tongue? Although the condition is âunsightly,â it is not harmful, the U.S. National Library of Medicine notes.
